Set in the natural landscape of Latvia, the cabin draws inspiration from traditional architectural forms while addressing modern living requirements. The design incorporates a saddle roof, reminiscent of the Blackheads House in Riga and the Ozolini Teamakers Retreat. Its purpose is to create a versatile space that connects the occupants to the surrounding environment, offering opportunities for retreat and reflection.

Design Elements and Layout

Measuring approximately 4.5 meters by 2.5 meters, the cabin has a total floor area of about 12 square meters. The central space accommodates various activities, including meditation, reading, writing, sleeping, and eating. A thoughtful arrangement allows for storage and auxiliary functions, making efficient use of the compact layout while providing a peaceful atmosphere.

Integration with Nature

Large doors and circular windows are key features, creating a strong link between the inside and outside. These openings invite natural light and fresh air into the space, enhancing the experience of living in harmony with nature. By opening the doors, occupants can easily transition from indoor comfort to outdoor serenity, offering a flexible way to adapt to changing weather conditions.

Materiality and Construction

Wood is the primary material used in the cabin's construction. This choice connects the building to local traditions while also supporting sustainable practices. The design incorporates pin joints and minimizes the use of metal fasteners, which helps maintain a clean look and ensures the building's durability. This approach reflects a respect for craftsmanship and the natural environment.

Functional Considerations

Practical aspects like hygiene and energy efficiency have also been addressed. A dry toilet is positioned for easy access without compromising interior space. To meet energy needs, the cabin features a mobile solar module that can be set up on the roof or positioned among surrounding trees. This feature promotes self-sufficiency and reduces reliance on external resources.

The cabin exemplifies a balance between form and function, creating a space that is adaptable and user-friendly. One notable design detail is the walk-in roof that provides expansive views of the landscape, enhancing the experience of retreat and contemplation. The overall design invites occupants to connect deeply with their environment, offering a thoughtful escape from everyday life.

`
Competition organisers

The Buildner’s Unbuilt Award 2025 is an international architecture competition dedicated to recognizing and celebrating the value of unrealized architectural designs. It invites architects, designers, and students worldwide to submit visionary projects that have not yet been constructed, highlighting the power of ideas and the creativity behind the design process. By focusing on unbuilt work, the competition aims to bring forward concepts that shape the future of architecture and push the boundaries of the profession. 

Participants can compete in three categories based on project scale: Small Wonders (up to 100 m²), Medium Marvels (101–999 m²), and Large Visions (over 1,000 m²). Each category winner will receive €20,000, and additional prizes include honorable mentions, student awards, and a special Best Presentation Award. Winning projects will gain significant international exposure through Buildner’s publicity campaign and a feature article on ArchDaily, providing a unique opportunity to showcase creative ideas to a global audience. 

The Buildner’s Unbuilt Award 2025 encourages entrants to submit any type of unbuilt project, from conceptual visions to detailed designs, celebrating bold innovation without the constraints of realization. Important deadlines: registration closes on October 30, 2025; submissions are due by November 20, 2025; winners will be announced on December 17, 2025.
